Abstract

Goals:; High NO oxidation of alpha-pinene to test products. Interested mainly in: organic nitrate yield from alpha-pinene at the high NO limit; -products formed in high NO oxidation of alpha-pinene to confirm for CIMS instruments what potential products formed in SOAS; -potential contribution of alpha-pinene derived nitrates to particle phase nitrates seen at SOAS. Secondary goals: potential effect of addition of seed aerosol on apparent loss rate of gas-phase compounds Summary:; The initial measurements of alpha -pinene and alkyl nitrates appeared to go well for PTR-MS and TD-LIF. ; Ozone began creeping up about ~30min into the experiment, reaching a maximum < 90 ppbv O3. NO was injected in after about an hour and 15 minutes after lights on to titrate out the ozone. Particle nucleation was observed roughly ; ~1hr 15min into the oxidation, potentially from an OH spike from the NO injection due to PNA buildup. ; After 08 ~5hrs of oxidation, the lights were turned off. Thirty minutes of dark sampling followed, at which ; point ammonium sulfate seed was injected into the chamber to determine ; what effect, if any, this will have on wall-loss of various species. Organization: 2014 FIXCIT Study; Lab Affiliation: California Institute of Technology; Chamber: Seinfeld chambers Experiment Category: Gas phase chemical reaction; Oxidant: Hydroxyl radical; Reactants: nitric oxide, ALPHA-PINENE, hydrogen peroxide; Reaction Type: Photooxidation; Relative Humidity: 5; Temperature: 26; Seed Name: No Seed; Pressure: 755
